Filesystem-level encryption, [1] often called file-based encryption, FBE, or file/folder encryption, is a form of disk encryption where individual files or directories are encrypted by the file system itself. This is in contrast to the full disk encryption where the entire partition or disk, in which the file system resides, is encrypted.
Typical file attributes may, for example, indicate or specify whether a file is visible, modifiable, compressed, or encrypted. The availability of most file attributes depends on support by the underlying filesystem (such as FAT , NTFS , ext4 ) where attribute data must be stored along with other control structures.
Open file backup. the ability to back up a file while it is in use by another application. See File locking. Remote store. backing up data to an offsite permanent backup facility, either directly from the live data source or else from an intermediate near store device. Restore time. the amount of time required to bring a desired data set back ...
Transparent Data Encryption (often abbreviated to TDE) is a technology employed by Microsoft, IBM and Oracle to encrypt database files. TDE offers encryption at file level. TDE enables the encryption of data at rest, encrypting databases both on the hard drive and consequently on backup media. It does not protect data in transit nor data in use.
The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS [1] that provides filesystem-level encryption.The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
EncFS is a Free FUSE-based cryptographic filesystem.It transparently encrypts files, using an arbitrary directory as storage for the encrypted files. [4] [5]Two directories are involved in mounting an EncFS filesystem: the source directory, and the mountpoint.
Encryption in transit protects data as it is being transmitted to and from the cloud service. [20] Encryption at rest protects data that is stored at the service provider. Encrypting data in an on-premises cloud service on-ramp system can provide both kinds of encryption protection. There are several options available to avoid security issues.
Object storage (also known as object-based storage [1] or blob storage) is a computer data storage approach that manages data as "blobs" or "objects", as opposed to other storage architectures like file systems, which manage data as a file hierarchy, and block storage, which manages data as blocks within sectors and tracks.
